【Abstract】 Compared with the conventional methods in computational fluid dynamics, such as the FDM and FEM, the Lattice Boltzmann Method(LBM) has the following advantages: the algorithm is simple and accurate, the pressure can be solved directly, and the method can be used to solve problems with complex boundaries and especially fits to parallel computation. New ways developed to deal with the boundary conditions and enhance the Reynolds number in the simulation promote the development of the LBM. The LBM has been widely applied to the simulation of problems in hydrodynamics, multiphase flows, heat transfer, and convectiondiffusion in two or three dimensions.更多还原
